I realize you are throwing out a concern, but this is not the first website I have ever built. I thwarted my first hotlinker back in 2001 when I made my first website. I know how to deal with them and more importantly how to track my visitors properly.
You didn't even try to understand my post. I was saying that people might not be interested in a camera but maybe a refreshment. It always depends on what you are selling. Picture viewing crowds won't easily buy expensive stuff, but might be good for lead generation.
Perhaps auction ads? You could always run just one paypop up ad per unique visitor. You'd make about $70 a day.
